I agree with Sue and don’t believe a complaint is warranted.
Agree with Irene’s statement:

“Bronchiectasis makes you prone to get infected with either or both (plus many other things). In that sense the Bronchiectasis is the reason you developed MAC. That is probably what the Dr was trying to say.”

I have bronchiectasis without MAC. I asked my very reasonable pulmonologist in Penn’s Bronchiectasis and MAC lung clinic about gardening. He told me he doesn’t think he should tell patients not to garden when there isn’t direct evidence at this point. However, he cautioned me to be careful if I do and wear a mask and gloves. Sue has given additional tips that I believe he would agree to.
